The Chain Checker CC-2 is a great device for determining if you need to replace your chain or rear cog, by accurately measuring the wear and stretch of any chain.

Top Features of the Park Tool Chain Checker

Measures Wear from 0.25% to 1%

Compatibility: 9/10/11-Speed compatible

With most manufacturers recommending to replace your chain at 0.75% stretch, the Chain Checker CC-2 will quickly and precisely let you know if you are over or under. As over worn chains can cause poor shifting and uneven drivetrain wear, having an accurate gauge to hand won't just save your chain, but can also save the full functionality of your bike.

Reading wear from 0.25% to 1%, the CC-2 is compatible with 9/10/11-speed chains and measures the stretch by simply inserting the pins between two links and pressing the swing-arm gauge tight to read your accurate reading in the gauge window.

(Note: For 9/10-speed chains, replace the chain at or before the 0.75% reading, and for 11/12-speeds, replace before the 0.5% reading. Always check with the manufacturer for any specific replacement instructions and recommendations.)

The tool doesn't fit

Hi,
I bought this chain checker, and cant seem to insert the two ends between the links of my chain, because the distance between the two pins of the tool is too long.
I have a 11 speed ultegra chain, only done about 1000kms.
Not sure if it doesn't fit because:
1. The tool was damaged/faulty - the pin on the black slider isn't perfectly perpendicular, but at a slight angle. Is that meant to be the case? The packaging looked to be in good condition.
2. My chain is incompatible - but I can't think of why this would be the case.
3. I'm using the tool incorrectly - But I am setting the adjuster to zero, and it still doesn't fit.

The pin on the black slider has to be perpendicular , but yes, I think this shabby
